SUMMARY OF THE INVENTION

In recent years, designability for appearance of displays such as liquidcrystal displays has been improved by advance of technology for displaypanels and electronic components. However, reducing thickness of thedisplays and narrowing of frames have been desired for furtherimprovements. Nevertheless, in a currently-available display, as in theabove-described Patent Literature 1, the housing containing the liquidcrystal panel, the rear-face housing in particular, is configured of aplurality of members such as the back chassis, the frame, the back-facecover, and the like, which has prevented a reduction in thickness.

Accordingly, it is desirable to provide a display whose thickness isallowed to be reduced.

A display according to an embodiment of the present technology includes:a display panel; and a back-face member having rigidity and provided ona back face of the display panel, the back-face member covering the backface, or the back face and other part of the display panel.

In the display according to the embodiment of the present technology,the back-face member covering the back face of the display panel isconfigured of a rigid member, and thus, it is possible to simplify amember configuration.

According to the display of the embodiment of the present technology, amember having rigidity is used as the back-face member of the displaypanel. Therefore, the configuration of the back-face member issimplified, and thereby, it is possible to reduce the thickness of thedisplay.

1. First Embodiment

FIG. 1 is a diagram illustrating a cross-sectional configuration of adisplay (a display 1) according to a first embodiment of the presentdisclosure, and FIG. 2 is an exploded perspective view illustrating anoverall configuration of the display 1. The display 1 may be, forexample, a liquid crystal display used as a television device. Thisdisplay 1 has a configuration in which: a backlight unit is contained ina housing 20 including a front bezel 21 (front-face member) and a backchassis 22 (back-face member); the backlight unit includes a displaypanel 10, an optical sheet 16, a light-guiding plate 17, a light source18, and the like; and the front bezel 21 and the back chassis 22 areadhered to each other with an adhesion member 23. On one end surface ofthe light-guiding plate 17, a plurality of LEDs are arranged as thelight source 18, and light emitted from this light source 18 irradiatesthe display panel 10 via the light-guiding plate 17, and is extracted asdisplay light toward the front bezel 21.

The display panel 10 displays an image such as a moving image or a stillimage, and may be, for example, a liquid crystal display panel having aliquid crystal layer 13 between two substrates, i.e., a TFT substrate 12and a CF substrate 14. Further, polarizing plates 11 and 15 allowingpolarized light in a specific direction to pass therethrough areprovided on a surface (front face (display surface) of the TFT substrate12 and a surface (back face) of the CF substrate 14, respectively, thesurfaces being opposite to surfaces where the liquid crystal layer 13 isprovided.

The TFT substrate 12 may be configured by, for example, arranging aplurality of pixel electrodes (not illustrated) in a matrix on a glasssubstrate. This TFT substrate 12 is provided with TFT (Thin FilmTransistor) devices driving the respective pixel electrodes, gate linesand source lines connected to these TFT devices, and the like (none isillustrated). The pixel electrodes may be formed of, for example, aconductive material having transparency such as ITO (Indium Tin Oxide),and are each provided for every sub-pixel (not illustrated) on the glasssubstrate.

The CF substrate 14 may have, for example, a color filter (notillustrated) with, for example, stripe-shaped filters of red (R), green(G), and blue (B) on a glass substrate, and may have a counter electrode(not illustrated) over almost the entire surface of an effective displayregion S2 on this color filter. The counter electrode may be configuredusing, for example, a conductive material having transparency such asITO, like the pixel electrodes described above. It is to be noted that,although not illustrated here, a spacer may be provided between thecounter electrode and the pixel electrodes on the TFT substrate 12 side,thereby keeping a gap between these substrates.

For example, in a case of a liquid crystal panel of a vertical alignmenttype, the liquid crystal layer 13 may include liquid crystal moleculeshaving negative dielectric constant anisotropy, and a polymer structureholding the liquid crystal molecules in proximity to an interface withan alignment film (not illustrated). A liquid crystal molecule has aproperty in which a dielectric constant in a major axis direction islarger than that in a minor axis direction. Based on this property, theliquid crystal molecule is arranged to allow the major axis of theliquid crystal molecule to be perpendicular to a substrate when a drivevoltage is OFF, and the liquid crystal molecule is oriented to allow themajor axis of the liquid crystal molecule to be parallel to thesubstrate when the drive voltage is ON. Thus, an image is displayed onthe liquid crystal display panel.

The optical sheet 16 is a sheet implementing various optical functionsfor the light being emitted from the light source 18 and irradiating thedisplay panel 10 through the light-guiding plate 17. As the opticalsheet 16, for example, sheets having a function of decomposing displaylight entering the display panel 10 from the light source 18 through thelight-guiding plate 17, into incident light and a polarized lightcomponent orthogonal to the incident light, a function of achieving awide viewing angle or prevention of coloring by ensuring a phasedifference between light waves, a function of diffusing the displaylight, and/or the like may be used as a single layer or as laminatedlayers.

The light-guiding plate 17 allows the light entering from the lightsource 18 to propagate therethrough, thereby guiding this light to thedisplay panel 10, and may have, for example, a rectangular flat shape.As a material of the light-guiding plate 17, a material having hightransparency such as glass may be used, but the light-guiding plate 17may be configured using other materials as long as the material allowsthe light from the light source 18 to propagate therethrough. Forexample, a light scattering material in which light scattering fineparticles are dispersed, or a light diffusion material may be employedto form the light-guiding plate 17. Specifically, acrylic resin,polymethyl methacrylate (PMMA), polycarbonate (PC), cyclic polyolefin(COP), or the like may be used. A shape, a size, a refractive index,density, density distribution, and the like of the light-guiding plate17 may be adjusted arbitrarily to obtain desirable characteristics.

For the light source 18, for example, in addition to a white LED (LightEmitting Diode), LEDs emitting light of red, blue, green, and the likemay be used. Further, other than a point light source such as LED, alinear light source such as a fluorescent light may be used. Asillustrated in FIG. 2, here, the light source 18 is provided on the oneend surface (undersurface) of the light-guiding plate 17, but is notlimited to this, and may be disposed along four sides of thelight-guiding plate 17.

The housing 20 may be, for example, substantially shaped like arectangular solid, and has two opposed surfaces, namely, a displaysurface and a back face, and also has side faces between these twosurfaces. In other words, the housing 20 in the present embodiment isconfigured of a front-face plate (the front bezel 21) and a back-faceplate (the back chassis 22). The front-face plate covers at least partof a front face of the display panel 10 (for example, a circumferentialedge portion of the display panel 10), and the back-face plate covers aback face and side faces between the front face and the back face of thedisplay panel 10.

The front bezel 21 is a frame used to fix the display panel 10 providedon the front-face side of the display panel 10, as described above. Anopening 21A of the front bezel 21 allows an image displayed on thedisplay panel 10 to be viewed. As a material of the front bezel 21, forexample, metal having high thermal conductivity, specifically, aluminum(Al), may be used. Besides this, iron (Fe), polycarbonate (PC), plasticin which ABS resin is added to PC, or the like can be used.

The back chassis 22 is also used to fix the display panel 10, whilecovering at least the back face of the display panel 10, and, here,covering the back face and the side faces between and the front face andthe back face of the display panel 10 as described above. As a materialof the back chassis 22, for example, metal having high thermalconductivity, specifically, Al may be used, as with the front bezel 21.Besides this, Fe or the like can be used.

In the present embodiment, the front bezel 21 and the back chassis 22are adhered to each other with the adhesion member 23 (sealant). Aconnection member (for example, a middle chassis or the like) used toconnect the front bezel 21 and the back chassis 22 to each other isomitted by integrating the front bezel 21 and the back chassis 22 withthis adhesion member 23. Examples of the adhesion member 23 may includeadhesives having sufficient adhesive strength and elasticity, which are,specifically, adhesives such as acrylic resin, urethane resin, epoxyresin, vinyl chloride resin, and modified silicone resin. Further, whenthe front bezel 21 and the back chassis 22 are adhered to each otherwith the adhesion member 23 as in the present embodiment, it ispreferable to configure the front bezel 21 and the back chassis 22 withthe same material, thereby improving bond strength and the like.Further, for example, a metallic material may be preferably used forshielding electromagnetic waves caused by various circuits andelectronic components provided inside the display 1. This reducesunnecessary radiation caused by the various circuits and electroniccomponents provided inside the display 1.

It is to be noted that, here, the adhesion member 23 also has a functionof serving as a sealing section of the display panel 10, by coveringpart of the side faces, the front face, and the back face of the displaypanel 10. Further, a spacer 24 is provided between the display panel 10and the back chassis 22. Thus, a space between the display panel 10 andthe back chassis 22 is secured and a region where the adhesion member 23is formed is partitioned. Furthermore, a piece of PORON 25 positioningthe light-guiding plate 17 and absorbing linear expansion of thelight-guiding plate 17 is provided between the spacer 24 and thelight-guiding plate 17, but may be omitted.

As illustrated in FIG. 2, the display 1 is completed by containing thedisplay panel 10, the optical sheet 16, the light-guiding plate 17, andthe like in the housing 20 configured of the front bezel 21 and the backchassis 22, and then by installing the housing 20 in a stand 19 providedwith a drive substrate of the light source 18, a speaker, and the like.The stand 19 may be, for example, a fixed base having a rectangular flatshape (a paperweight structure), but is not limited to this, and mayhave a tilt-swivel mechanism capable of changing an orientation of ascreen of the display panel 10 vertically and laterally.

In this display 1, when the light emitted from the light source 18enters the display panel 10 through the light-guiding plate 17 and theoptical sheet 16, the entered light passes through the polarizing plate11 and then passes through the liquid crystal layer 13 while beingmodulated for every pixel, based on an image voltage applied betweentransparent electrodes of the TFT substrate 12 and the CF substrate 14.After passing through the liquid crystal layer 13, the light passesthrough the color filter, thereby being extracted as color display lightto an outer side (a surface side) of the polarizing plate 15.

FIG. 7 illustrates a cross-sectional configuration of a display 100 of arelated art. In the display 100, a display panel 110, an optical sheet116, and a light-guiding plate 117 are contained in a housing 120, as inthe display 1 of the above-described present embodiment. This housing120 is configured of a front bezel 121, a back chassis 122, a topchassis 123, and a middle chassis 124. In the display 100 of the relatedart, the top chassis 123 and the middle chassis 124 are disposed betweenthe front bezel 121 and the back chassis 122, and the front bezel 121and the back chassis 122 are connected with this top chassis 123 and themiddle chassis 124. Specifically, the top chassis 123 and the backchassis 122 are fixed with screws (not illustrated) with the middlechassis 124 in between. A panel module assembled in this way issandwiched between the front bezel 121 and a rear cover 125, and isfixed with screws (not illustrated). Therefore, a region used to fix theabove-described housing 120 with the screws has been necessary in aframe region S1 of the display 100. In addition, the number ofcomponents including the top chassis 123, the middle chassis 124, thescrews, and the like is large, which increases weight.

In contrast, in the display 1 of the present embodiment, the housing 20has two components, namely, the front bezel 21 and the back chassis 22,and the front bezel 21 and the back chassis 22 are adhered to each otherwith the adhesion member 23. In other words, the region used to fix thehousing 120 with the screws may not necessarily be secured in the frameregion S1 as in the display 100 of the related art. Therefore, it ispossible to reduce the frame region S1. In addition, connection members(the top chassis 123, the middle chassis 124, and the screws) connectingthe front bezel 121 and the back chassis 122 may be unnecessary.Therefore, cost is allowed to be slimmed down, and weight of the display1 is allowed to be reduced.

As described above, in the display 1 of the present embodiment, thefront bezel 21 and the back chassis 22 configuring the housing 20 areadhered to each other with the adhesion member 23. Therefore, it ispossible to reduce a region used to connect the component members of thehousing 20 in the frame region S1. In other words, it is possible tonarrow the frame of the display 1.

Moreover, a connection member used to connect the component members (thefront bezel 21 and the back chassis 22) of the housing 20 may beunnecessary. Therefore, it is possible to slim down the cost and reducethe weight of the display 1.

The second to fifth embodiments will be described below. It is to benoted that the same elements as those of the first embodiment will beprovided with the same characters and thus, the description thereof willbe omitted.

2. Second Embodiment

FIG. 3 illustrates a cross-sectional configuration of a display 2according to the second embodiment of the present disclosure. Thedisplay 2 includes the display panel 10, the optical sheet 16, and thelight-guiding plate 17 contained in a housing 30, and the display 2 isdifferent from the display of the first embodiment in that this housing30 is configured of a front bezel 31 (front-face member), a rear plate32 (back-face member), a top chassis 33, and a middle chassis 34.

As in the above-described first embodiment, the housing 30 may be, forexample, substantially shaped like a rectangular solid, and has twoopposed surfaces, namely, a display surface and a back face, and alsohas side surfaces between these two surfaces. In other words, in thepresent embodiment, the front bezel 31 and the rear plate 32 areconnected with the top chassis 33 and the middle chassis 34. The frontbezel 31 serves as a front-face plate covering the display surface(front face) and the side faces of the display panel 10. The rear plate32 serves as a back-face plate covering a back face of the display panel10.

The front bezel 31 is a frame used to fix the display panel 10, as inthe above-described first embodiment. An opening 31A of the front bezel31 allows an image displayed on the display panel 10 to be viewed. As amaterial of the front bezel 31, for example, metal having high thermalconductivity, specifically, Al may be used. Besides this, Fe,polycarbonate (PC), plastic in which ABS resin is added to PC, or thelike may be used.

The rear plate 32 is provided to cover the back face of the displaypanel 10 as described above, and also to support the entire display 2.The rear plate 32 is a member having rigidity. Further, a member havinga high Young's modulus or a low linear expansion coefficient may bepreferably used. Specifically, glass, ceramic, or metal such as Al andFe, having a thickness of about 1.0 mm to about 3.0 mm both inclusivemay be used. In the present embodiment, the member having rigidity isused as the back-face member of the housing 30. Therefore, it ispossible to support the entire display 2 without using the back chassis22, a support member to support the display 1 such as an outer member(for example, the rear cover 125 (see FIG. 7)), and/or the like.

Further, on the entire back face of the rear plate 32, a light-shieldingfilm 32A is provided to prevent external light from entering into thedisplay 2. Examples of this light-shielding film 32A may include a resinfilm such as a black film into which a black coloring agent is mixed andwhich has an optical density of 1 or more.

The top chassis 33 and the middle chassis 34 are provided to connect thefront bezel 31 and the rear plate 32 to each other as described above.Examples of a material of each of the top chassis 33 and the middlechassis 34 may include metal such as Al and Fe, similarly to thematerial of the back chassis 22 in the above-described first embodiment.It is to be noted that the top chassis 33 and the middle chassis 34 maybe molded using a material having thermal conductivity lower than thatof metal, which is, for example, a synthetic resin or the like. Use ofthe material having low thermal conductivity suppresses transmission ofheat produced in the light source 18 to the front bezel 31, and makes itpossible to radiate heat from the back-face side efficiently, whilesuppressing a temperature rise on the front-face side of the display 2.

In this display 2, light emitted from the light source 18 enters thedisplay panel 10 through the light-guiding plate 17 and the opticalsheet 16, in a manner similar to that in the above-described firstembodiment. This entered light passes through the polarizing plate 11,and then passes through the liquid crystal layer 13, while beingmodulated for every pixel, based on an image voltage applied betweentransparent electrodes of the TFT substrate 12 and the CF substrate 14.After passing through the liquid crystal layer 13, the light passesthrough a color filter, thereby being extracted as color display lightto an outer side (a surface side) of the polarizing plate 15.

FIG. 7 illustrates the cross-sectional configuration of the display 100of the related art. However, on the back face of this display 100, aback-face housing including the back chassis 122 and the like, and theouter member including the rear cover 125 and the like are provided tocontain the display panel 110 and support the entire display 100.

In contrast, in the display 2 of the present embodiment, the back-faceplate (the rear plate 32) having rigidity is used for the entire backface of the display panel 10, of the housing 30 containing the displaypanel 10. This allows one member to serve in place of a plurality ofmembers including the back chassis 122, the rear cover 125, and the likeused to support the typical display 100.

As described above, in the display 2 of the present embodiment, thematerial having rigidity is used for the back-face plate covering theentire back face of the display panel 10. Therefore, the display panel,which is supported using, in the related art, the plurality of memberssuch as the back chassis 122 and the rear cover 125, is allowed to besupported with one member (the rear plate 32). In other words, it ispossible to reduce the thickness of the display 2.

Further, it is possible to reduce the number of components of thesupport members configuring the display 2 as in the above-describedfirst embodiment. Therefore, cost is allowed to be slimmed down, and theweight of the display 2 is allowed to be reduced.

3. Third Embodiment

FIG. 4 illustrates a cross-sectional configuration of a display 3according to a third embodiment of the present disclosure. The display 3includes the display panel 10, the optical sheet 16, and thelight-guiding plate 17 contained in a housing 40, and the display 3 isdifferent from the first and second embodiments in that this housing 40is configured of a front glass 41 (front-face member, transparentplate), a rear plate 42 (back-face member), and a decoration frame 43,the front glass 41 being provided on a front face of the display panel10 with a sealing layer 44 in between. It is to be noted that the frontglass 41 (front-face member), the rear plate 42 (back-face member), andthe decoration frame 43 are adhered to one another with the adhesionmember 23.

The front glass 41 is a plate-like member provided on the entire frontface of the display panel 10 with the sealing layer 44 in between asdescribed above, and is configured using a material of hightransparency, such as glass, polycarbonate (PC), and plastic in whichABS resin is added to PC. The front glass 41 has, for example, athickness of about 0.5 mm to about 3.5 mm both inclusive, and protectsan display region S2 of the display panel 10, and also supports thedisplay 3 in cooperation with the rear plate 42 which will be describedlater.

The rear plate 42 is provided to cover the entire back-face side of thedisplay panel 10 as described above, and also to support the entiredisplay 3, as in the above-described second embodiment. The rear plate42 is a member having rigidity, and may be made of, for example, glassor metal such as Al and Fe having a thickness of about 1.0 mm to about3.0 mm both inclusive. In addition, the front glass 41 and the rearplate 42 are adhered to each other with the adhesion member 23 asdescribed above. Therefore, materials having the same or similarproperties may be preferably used as the materials of the front glass 41and the rear plate 42. Specifically, glass may be desirably used in viewof transparency desired for the front glass 41, rigidity desired for asupport member of the display, and a difference in expansion coefficientwith respect to the display panel 10. Further, on the entire back faceof the rear plate 42, a light-shielding film 42A is provided to prevententrance of external light into the display 3, as in the above-describedsecond embodiment.

The decoration frame 43 is provided to cover side faces between a frontface and a back face of the display 3, and also to seal the adhesionmember 23 used to connect the front glass 41 and the rear plate 42 toeach other. As a material of the decoration frame 43, for example, thematerial of the back chassis 22 in the above-described first embodiment,metal such as Al and Fe, or the like may be used. It is to be noted thatthe decoration frame 43 may be a flat-plate-like member, but asillustrated in FIG. 4, the decoration frame 43 may have a protrusionsection 43A in a sealing direction of the adhesion member 23. Byproviding this protrusion section 43A, an amount of the adhesion member23 used to adhere the front glass 41 and the rear plate 42 to each othermay be reduced. In addition, positioning of members configuring thedisplay 3 (for example, see FIG. 5) may be performed by appropriatelyadjusting a position where the protrusion section 43A is formed.

The sealing layer 44 is provided to seal a space between the displaypanel 10 and the front glass 41, and may be configured using, forexample, resin or the like having a photo-hardening property, athermosetting property, a moisture-curing property, an aerobic-curingproperty, or a hot-melt property, or any combinations of theseproperties. It is to be noted that the sealing layer 44 may be omitted,but by sealing the space between the display panel 10 and the frontglass 41 with the sealing layer 44, strength is improved and also imagequality is improved. Moreover, designability is also improved.

In the display 3 of the present embodiment, the materials havingrigidity and the same or similar properties are used for the front glass41 and the rear plate 42 configuring the housing 40, and the front faceand the back face of the display panel 10 are covered by the front glass41 and the rear plate 42. This simplifies a back-face member provided onthe back-face side of the display panel 10, such as a back-face housingand an outer member, and thereby, it is possible to reduce thickness ofthe display 3. Furthermore, since the front glass 41 and the rear plate42 are adhered to each other with the adhesion member 23, it is possibleto reduce the frame region S1. In other words, it is possible to reducethe thickness of the display 3 and to narrow the frame thereof at thesame time.

4. Fourth Embodiment

FIG. 5 illustrates a cross-sectional configuration of a display 4according to a fourth embodiment of the present disclosure. In thedisplay 4, the display panel 10 and the optical sheet 16 are containedin a housing 50, and this housing 50 is configured of a front glass 51(front-face member) provided on a front face of the display panel 10with the sealing layer 44 in between, a light-guiding plate 52(back-face member), and a decoration frame 53. In the display 4 of thepresent embodiment, the light-guiding plate 52 is used as a back-facemember, which is different from the above-described first to thirdembodiments. It is to be noted that the front glass 51, thelight-guiding plate 52, and the decoration frame 53 are adhered to oneanother with the adhesion member 23.

As in the above-described third embodiment, the front glass 51 isprovided on the front face of the display panel 10, and is made of amaterial having high transparency, such as glass, polycarbonate (PC),and plastic in which ABS resin is added to PC. The front glass 51 mayhave, for example, a thickness of about 0.5 mm to about 3.5 mm bothinclusive, and protects the display region S2 of the display panel 10.Also, the front glass 51 supports the display 4 in cooperation with thelight-guiding plate 52 which will be described later.

The light-guiding plate 52 covers the entire back face of the displaypanel 10 as described above, and may be configured using a materialhaving the same or similar property as that of the above-described frontglass 51, which may be, for example, a member having rigidity andcapable of supporting the entire display 4, like the third embodiment.Specifically, for example, glass, metal such as Al and Fe, or the likehaving a thickness of about 1.0 mm to about 3.0 mm both inclusive may beused. Further, on the entire back face of the light-guiding plate 52, alight-shielding film 52A is provided to prevent entrance of externallight into the display 4. This light-shielding film 52A may beconfigured using, for example, a resin film such as a black film intowhich a black coloring agent is mixed and which has an optical densityof 1 or more, as in the above-described second and third embodiments. Ofthese, a black resin film may be preferable to be used, because thelight-shielding film 52A is allowed to be formed easily at a low cost.

The decoration frame 53 is provided to cover side faces between a frontface and a back face of the display 4, and also to seal the adhesionmember 23 connecting the front glass 51 which is the front-face memberand the light-guiding plate 52 which is the back-face member to eachother, as in the above-described third embodiment. As a material of thedecoration frame 53, a material similar to that in the above-describedthird embodiment may be used.

In the display 4 of the present embodiment, the light-guiding plate 52configured using the material having transparency and rigidity isprovided as a back-face plate covering the back face of the displaypanel 10. Therefore, it is possible to further reduce thickness of thedisplay 4, in addition to achieving effects of the above-described thirdembodiment. Further, it is possible to reduce the number of componentsconfiguring the display 4. Therefore, an effect of further reducing costis achieved.

5. Fifth Embodiment

FIG. 6 illustrates a cross-sectional configuration of a display 5according to a fifth embodiment of the present disclosure. In thisdisplay 5, the front-face member is not provided, and the display panel10 and a rear plate 62 are connected to each other with a middle chassis64. In other words, a housing 60 that contains the display panel 10, theoptical sheet 16, the light-guiding plate 17, a reflective sheet 65, andthe like that configure the display 5 is configured of the rear plate 62and the middle chassis 64, and the display panel 10 is exposed at thefront face of the display 5. It is to be noted that the reflective sheet65 reflects, in the front-face direction, light that propagates in thelight-guiding plate 17 and is reflected in the back-face direction, andmay be omitted. The present embodiment is different from theabove-described first to fourth embodiments in that the front-facemember is not provided.

The rear plate 62 is provided to cover the back face of the displaypanel 10 as described above, and also to support the entire display 5.The rear plate 62 is a member having rigidity as in the above-describedsecond embodiment and the like. Further, a member having a high Young'smodulus or a low linear expansion coefficient may be preferably used forthe rear plate 62. Specifically, glass, ceramic, or metal such as Al andFe, having a thickness of about 1.0 mm to about 3.0 mm both inclusivemay be used. It is to be noted that the rear plate 62 may desirably havelight shielding properties, and for example, a light-shielding film maybe provided on the entire back face of the rear plate 62 as in theabove-described second embodiment. This prevents entrance of externallight into the display 5. Examples of the light-shielding film mayinclude a resin film such as a black film into which a black coloringagent is mixed and which has an optical density of 1 or more.

The middle chassis 64 are provided to connect the display panel 10 andthe rear plate 62 to each other as described above. As a material of themiddle chassis 64, for example, the material of the back chassis 22 inthe above-described first embodiment, metal such as Al and Fe, and/orthe like may be used. It is to be noted that a material having lowerthermal conductivity than metal, for example, a material such as asynthetic resin may be used for molding. Further, the middle chassis 64may be configured, for example, of four members that are dividable intotop, bottom, right, and left members when the display panel 10 isrectangular.

In the present embodiment, the housing 60 is configured of the rearplate 62 and the middle chassis 64 as described above. Specifically, therear plate 62 and the middle chassis 64 are connected to each other byfixing, for example, an affixing plate 66 made of metal at apredetermined position of the rear plate 62 with the use of adouble-sided tape and/or the like, and fixing the affixing plate 66 andthe middle chassis 64 to each other with the use of a screw 67. Further,the middle chassis 64 and the display panel 10 are connected to eachother, for example, with the use of a photocurable resin, a double-facedtape, and/or the like. It is to be noted that a decoration frame 63 maybe provided on a surface of the middle chassis 64 in view ofreinforcement of the housing 60 and designability, as in theabove-described third embodiment.

It is to be noted that, in the present embodiment, for example, aframe-like reinforcing frame 68 may be provided in a space between thereflective sheet 65 and the rear plate 62 that is caused by the affixingplate 66 provided to connect the rear plate 62 and the middle chassis 64to each other. This reinforcing frame 68 may preferably have rigidity,and a member having a high Young's modulus or a low linear expansioncoefficient may be preferably used therefore, as with the rear plate 62.Specifically, glass, ceramic, or metal such as Al and Fe may be used.Further, the reinforcing frame 68 and the rear plate 62 may bepreferably fixed to each other, for example, with the use of adouble-faced tape. For example, in a case where the rear plate 62 isformed of glass in the display 5, provision of the reinforcing frame 68may allow the display 5 to stand by itself even when the glass isbroken. It is to be noted that, although the reinforcing frame 68 has aframe-like shape in this example, the shape of the reinforcing frame 68is not limited thereto as long as the shape allows self-standability ofthe display 5 to be improved. For example, the reinforcing frame 68 mayhave a plate-like shape, a fence-like shape, or a lattice-like shape.

As described above, in the display 5 according to the presentembodiment, the front-face member is not provided, and the display panel10 and the rear plate 62 that is formed of a material having rigidityand serves as the back-face member are connected to each other with themiddle chassis 64. Therefore, it is possible to further reduce thethickness in addition to the effects in the above-described secondembodiment. Further, it is possible to reduce the number of componentsconfiguring the display 5. Therefore, cost is allowed to be furtherslimmed down, and the weight of the display 5 is allowed to be reduced.

The present technology has been described using the first to fifthembodiments, but the present technology is not limited to theabove-described embodiments and may be variously modified. For example,the liquid crystal display is used as an example of the display 1 in theabove-described embodiment, but a plasma display, an organicelectroluminescence display, or the like may be adopted.

Further, each of the members and thicknesses in the above-describedembodiments is described as an example. Not all the members maynecessarily be provided, or other members may be further provided. Forexample, as a system of radiating heat produced by the light source 18,a heat sink may be adhered to part or all of the back face of thedisplay, for example, to a lower end part where the light source 18 isprovided. For the heat sink, metal superior in thermal conductivity maybe desirably used, and, for example, a material formed by molding ablock made of Al or the like may be used. Further, in the displaydescribed in each of the above-described embodiments, the polarizingplate is provided on a surface of the display panel, but is not limitedto this example, and may be, for example, provided on a surface of thefront glass.
